Electromagnets are created by running an electrical current through a conductive metal. An electrical current causes the rapid movement of electrons, which creates a magnetic field. Electromagnetic fields can be created by running an electrical current through any metal, including non-ferrous conductive ...

Why are electromagnets used? Why are ocean currents important? Why is the Prime Meridian important? Why is cosmology important? Why is the Coriolis force stronger at the poles? Why do magnets lose their magnetism? Why is stratigraphy important?
"For steel we used electromagnets to pick up the parts," Blosser says. "That obviously wouldn't work with aluminum because it's nonferrous, so we had to go to the vacuum system." I walk around to the output end of the press, where F-150 fenders are dropping onto the conveyor belt ...
Before we tackle why electricity and magnetism are related, first we must understand what electricity and magnetism are when regarded separately (though that is truly a difficult thing to do because they are so closely related). Electricity involves the flow of electrons. Magnetism is the ...
Why do electromagnets have a south and north pole? Why space between lines in hydrogen line spectra gets smaller ? Why do electrolysis use electrical current? Explain briefly. Why do metals conduct heat and electricity? Why do copper (II) sulfate crystals not conduct electricity? Explain why cop...
Why are electromagnets used? Why do you analyze ELISA samples in triplicate? Why do seismometer oscillate back and forth? Why does a protoplanetary disk flatten? Why do scientists need a standard system of measurement? How does ultrasound imaging work? For paper chromatography, why was pencil used...
Insulators are materials that can trap heat. People can use insulators to survive very cold conditions since they allow a person to retain a lot of the heat energy generated by their metabolic processes.Answer and Explanation: Plastics are good insulators because they do not contain free electrons...
Why are electromagnets used? Why does the salinity of seawater remain constant? Why is the absence of cilia harmful? Why is meristem tissue important? Why do phospholipids form a double layer? Why don't placental mammals have photolyases? Why is the fovea indented? Why is superposition importan...
